AM5726: AM5716 inconsistency of bootup
HI,
I have a PCB of our own design which uses AM5716 and eMMC IS21ES04G-JCLI. (4GB eMMC)
The PCBA runs quite well in previous batches of production.
Recently we built a new batch of PCBA, which uses IS21ES08G-JCLI for replacement due to component shortage.
All the PCBAs have the below error when it starts to run:
Which seems the EXT4-FS (mmcblk0p2) error occurs for every PCBA.
My question is:
What could possibly be the cause of the problem? since the replacement eMMC is fully compatible with the original design except for the size .
How can I conduct the troubleshooting for this problem?
Thanks in advance.
Regards

您问题中有些字符显示不出来，麻烦重发一下。
另外，请问用的是那个版本的Processor SDK? 是自己的开发板还是TI的EVM板？

Hi, Thanks for the reply.
It is a PCBA of our own product.
这个PCBA已经进入批量生产阶段，前面的几批板子生产都没有问题。
在最新的一批板子中， 我们用IS21ES08G （8GB eMMC）代替了以前设计使用的IS21ES04G （4GB eMMC），两者应该是完全兼容的。
在载入启动后，有以下问题。
请问这可能是什么原因？是eMMC的问题还是其他问题？
REGARDS，

请问使用的是否是最新的processor SDK? 请看一下是否按照下面的emmc启动模式分区和配置的？https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components_U-Boot.html#sd-emmc-or-usb-storage
